Hematite, also spelled as haematite, is a common iron oxide with the formula Fe 2 O 3 and is widespread in rocks and soils. Hematite crystallizes in the rhombohedral lattice system, and it has the same crystal structure as ilmenite and corundum. Hematite and ilmenite form a complete solid solution at temperatures above 950 °C (1,740 °F).

The application of dry magnetic separation has not been explored much for hematite which is abundant in nature. The details about high-intensity magnetic separation and its application in iron ore beneficiation are narrated further.
